What KIND of 56k internal V.92 Data/Fax/voice modem do you have?


I typically solve the 'Winmodem' problem by using an External Modem. I
have used a
ActionTEC 56K External for over 5 years now without a single hiccup.


Internal verses External is a religious subject, with all kinds of "pro"
and "con" reasons. Some claim they are better for this reason, with the
other party claiming that their stance is better for a different reason.
Neither will ever agree that the other may have a point.


I have NEVER had any luck with internal Winmodems for linux, be it RH,
Suse, Mandrake, etc...


You won't get a disagreement from me. I've got better things to use my
CPU cycles for than to emulate hardware that the manufacturer left out
to save a buck on manufacturing costs. But not all internal modems are
winmodems. Using Rob Clark's rather dated web page:

[compton ~]$ grep -E '^ (LM|OK|WM|\?) ' isa_list.txt.12.02.04
pci_list.txt.12.02.04 | cut -d' ' -f4 | sort | uniq -c | column
438 ? 80 LM 174 OK 277 WM
[compton ~]$

Admittedly, most of those identified as OK were ISA (as was the original
US Robotics model 5683 Winmodem - the one that started it all), none the
less there are at least 17 real hardware modems using the PCI bus.

The problem with _external_ modems is that modern systems are less likely
to have the classic RS-232 serial ports. Remember, it's an old fashioned
specification that originated in 1969 - over 12 years before the IBM PC.
The replacement is USB, and that interface is fast enough for winmodems.
That old web page noted

[compton ~]$ grep -E '^ (LM|OK|WM|\?) ' usblist.txt.12.02.04 | cut -d' '
-f4 | sort | uniq -c | column
69 ? 4 LM 8 OK 10 WM
[compton ~]$

and you're back to the compatibility problems. Yes, there are USB to
RS-232 adapters, but how much longer do you expect modem manufacturers
to build RS-232 modems?

Old guy

Okay,

This got me thinking (dangerous) and looking at the connection between my modem and
firewall (even more so...). My modem has a 9-pin D-shell connection that attaches to the
back of my firewall (an old Gateway PC with a 233MHz Pentium Pro running Smoothwall 2.0).
After that, my firewall acts as the DHCP server and broadcasts to other workstations on my
network. I suspect that the RS-232 connection has been going away from sometime now.
But, it IS a standard that is used in a number of places (primarily the Telco industry).
